Details:

The Magpul Back Up Sight (MBUS) is a must for any AR-15/AR-10 owner. Constructed from virtually indestructible polymer, these sights can serve as a back up to your scope or red dot. They also make an excellent light weight primary sight.

Since the Magpul MBUS front sight offers the same height-over-bore distance as the standard A2 iron sights, AR-15/AR-10 devotees will feel right at home with these sights. The sight post is protected by two "wings" on either side to prevent it from being damaged or bumped out of zero.

When the sight is not in use, it can be folded down. When it is needed again, you can instantly pop this spring loaded sight back into position with no loss of zero! The MBUS is optimized for the AR-15 and M-16 family of rifles, but it will also fit any weapon that features a 1913 Picatinny rail.

    Great back up sights if your primary optics fail. Easy to install and adjust within minutes. Have these installed on all of my AR builds.
